GEMÜ 312

The GEMÜ 312 pneumatically operated 3/2-way globe valve provides precision mixing and distribution for inert gaseous and liquid media. The GEMÜ 312 features a 1.4408 stainless steel flanged body and manages process temperatures from -10°C to 180°C at pressures up to 40 bar within DN 15 to 100 automated systems. Key Performance Capabilities: Maintenance Reduction: The GEMÜ 312 uses a self adjusting gland packing and integrated wiper ring to maintain a reliable valve spindle seal, extending service life and preventing costly media leakage. System Consolidation: The GEMÜ 312 multi port design combines mixing, separating and aerating functions into a single unit, reducing the total component count to lower initial system procurement and installation costs. Pressure Integrity: The GEMÜ 312 flanged body adheres to EN 1092 standards, supporting PN16 and PN40 pressure ratings to ensure system security in high pressure industrial fluid control applications. Reliable Actuation: The GEMÜ 312 robust aluminium piston actuator supports standard 5.5 to 7.0 bar control pressures, ensuring consistent valve plug positioning to eliminate process variability and downtime. Safety & Compliance: Bubble-Tight Sealing: The GEMÜ 312 achieves leakage rate A according to DIN EN 12266-1 standards using PTFE seat seals, guaranteeing zero leakage for inert air and gaseous media. Quality Assurance: Every GEMÜ 312 valve body manufactured from 1.4408 investment casting provides high chemical resistance, adhering to strict ISO 9001 quality management protocols to ensure long term operational reliability. Defined Control States: The GEMÜ 312 pneumatic actuator supports Normally Closed (NC) functions to guarantee a secure valve position during a loss of control medium, protecting downstream equipment from damage. Note: Maximum operating pressures and media temperature limits for the GEMÜ 312 depend strictly on the selected flange connection code, nominal size and seat seal materials.
